Easterly wave making its way across Atlantic...

On August 1, a potent African easterly wave exited the coast and is now centered near 35W.  There is evidence of a mid-level circulation in the satellite imagery, and a hint of a weak surface circulation based on microwave scatterometer and visible satellite data.  It has also maintain a small cold cloud shield over the center of the mid-level circulation.  This system, though poorly organized now, could become better organized in the coming days.  It would reach the Lesser Antilles this weekend if it holds together.

Elsewhere, the basin is quiet.  However, this is not atypical... climatologically, there is only one tropical storm by this date, and no hurricanes.  The first name on this year's list is Ana.
